Google Ad Manager DAI service has already been restored for some users, and we expect a resolution for all users in the near future. Please note this time frame is an estimate and may change. The affected users are able to access Google Ad Manager DAI, but are seeing error messages, high latency, and/or other unexpected behavior. Ad Manager DAI streams return internal error. Engineering has identified the root cause and deployed a mitigation covering most streams, while work continues to address the remaining impact. There is currently no workaround.
